So I bought 2 angels 6 months ago, pretty much the same size, likely from the same breedingā¦ they were buds, no aggression between them, in the same tank, and fed the sameā¦ 6 months later, one is 50% bigger than the otherā¦ curious if the size difference could be sexual, as itās supposed to be hard to tell the sexes apartā¦ Iām not trying to breed them, just curious if that could be a way of telling them apart long term??? They are both Zebra Lace, and lucky for me the prettiest one is the biggest ( they are both gorgeous ) and likely about half grown??? The bigger one is like 4 inches nose to tail, and 6 inches highā¦ the smaller like 3.5 inches nose to tail, and 5 inches highā¦ they are in a 55 gallon South American community tank, with lots of tetras and dwarf cichlids
